Patented can. 21, less.

Be it known that I, SALVADOR Mounts, a citizen of the Republic of Mexico, residing at Calle 4 No. 158, Chihuahua, Mexico, have invented a new and useful Feed and Delivery Attachment for Printing-Presses, of whicithe following is a specification; 7

This invention relates to niechan'ismfor feeding paper to, and removing it from, printing presses and it is designed for use in connection with various forms of job presses.

The object of the invention is to utilize suction means for conveying paper from a suitable delivery tableand depositing it at a proper oint upon a press.

A still further object is to provide similar means for subsequently removing the paper from the press and depositing it upon. a re ceiving table.

Another object is to rovide means for controlling the suction wit iin the feed and delivering mechanism so that the same will he established and interrupted at proper intervals during the operation of the machine.

With these and other objects in viewthe invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully describedand pointed out in the claims. i In the. accompanying drawings is shown the preferred form of the invention. 7 I In said drawings: Figure 1 is a front eleva tion of the improved feeding and delivering, mechanism constituting the subject matter of the present invention; Fig. 2 is a side elevation thereof and showing a portion of 'a press, all but a part of the supply table being removed; Fig. 3 is a side elevation of the sup-- ply table, parts thereof being shown in section; Fig. 4 is a plan view of the swinging arms and adjacent parts of the feeding and delivering mechanism, the relative positions thereof and of the supply and receiving tables being shown .diagrannnatically; Fig. 5 is an enlarged plan view of a portion of one ofthe arms and its supporting track, one of the positions of the arm and track being disposed in dottc-zdlincs; Fig. 6 is a side elevation of the parts shown in Fig. 5 and showing by dotted 8 is a rear elevation of the back of the supply table; Fig. v9 is a plan view of the rate et mechanism for actuating the su ply table; Fig. 1'O'is a longitudinal section t rough one ofthe'suction cups; and Fig. 11 is a section on line acx, Fig. 6.

' Referring to the figures by characters of reference, 1 is a portion of the frame of a printing press the same so porting a feed table 2 and also carr ung a argc gear 3 which meshes with a smal gear l. This small gear has an eccentric 5 secured tothe shaft 6 thereof, said eccentric serving to actuate a pump rod 7 Working within a pump cylinder 8. This pump is connected to a tank 9 by means of a pipe 10 and is adapted to Withdraw air from the tank so as to create suction.

Secured to the frame 1 in any desired manner is a supplemental frame 1 l mounted upon inclined supports 12 and connectedtothe table 2 in any desired manner as by means of arms 13. The supplemental iraina 11 has a main shaft 14 journaled therein and carrying a large drive gear 15 Winch is of the "same size .as the gear 3 and meshes therewith. The

two gears will therefore rotate at the same speed. A small gear 16 is secured to one end portion of the shaft 14 and meshes with a similar gear 17 securedto a stud shaft 18 journaled within. a hanger 19 formed with the supplemental frame '11. An eccentric 20 of the feeding mechanismv A rotates with the gear 17 and has a groove 21 inwhich is adaptend of this arm projectsat all times above the plane occupied by the table 2.

The upper end of the hanger 19 forms an car 27 to which is pivotally connected a flange 28 depending from one edge of the central portion of a rail 29. As shown particularly in Figs. 2 and 6 this rail has its end portions concave while its intermediate portion is convex longitudinally and movably mounted on the rail is a carriage consisting of an upstanding plate or body portion 30 having rollers 31 extending laterally therefrom and adapted to bear upon the upper face of the rail, and another roller 32 extending laterally therefrom and ada ted to bear upon the lower face of the rail, t ese rollers being arthc.spring, as shown in Fig. 6 is secured to: V This spring is adapted to hold the arm 37 normally in position over the table 2 fthe arm.

.ward from a bracket. 42 19.

39 and has a head 44 in which is 'securedone i i'ormecl with a plurality ranged preferably as shown in Figs. 1 aud o and the lower roller 37 being mfovahly mounted in a slot 32 and constantly drawn upward against the rail by means of a spring One end of the body 30 is connected to the u per end ol arm. 26 by means oia link 34. ..n view of this arrangement of parts it is obvious that when the yoke 23 is swung upon its pivot 25 by the rotation of eccentric 20 the arm 26 will pull or push upon link 34 and cause the carriage to travel'longitudinally=along the rail 29. In order that an up and down movement of the carriage may he produced it is necessary to rock the. rail 29 at predetermined intervals. This result is ob tained by providing the tubular arm 35 which is pivotally connected as at 36 to yoke 23 and has a rod. 37 slidably mounted. therein and pivotally connected to the flange 28 of the rail 29. A spring 38 is arranged within the arm 35 and constitutes a cushion to gradually stop the movement rockedin any direction.

Mounted upon the carriage 30' so as to g swing in a horizontal plane is an arm 39- carrying a gear 40 adapted 'to mesh at all times with a series of pins 41 extending upsecured-to the hanger A. stem 43 constitutes the pivot of arm end of a coiled spring 45. The other end of and when the 40 and armj39ar'e turned upon their pivots the spring 45 will be'ten. sioned and will tend to return the parts to their normal positions. Thetubular arm'46 extends downward from and carries an inverted of apertures 48 in the bottom face thereof. I l v A pipe 4.9 is secured upon arm 39 and connected to the arm 46 and another pipe 50 is secured on the arm 26 and yoke 23 the two pipes being connected by a flexible tube 51. Arranged upon the hanger 19 is a valve casing 52 having an inlet 53 and an outlet The inlet has a pipe 55 extendin from} it and connected to the pipe 50 by a eX'ible tube 56 and a pipe 57 extends from the outlet 54; to the tank 9. A plug valve 58 is rotatably mounted within the casing and is provided with a stem having an outstanding pin 60 thereon adapted to work within a slot 61 formed in one end'of an arm connected to the yoke 23. Valve 58 has a passage 63 therein which is adapted when the stenr59 is in one position to place the inlet 53 and the outlet 54 in communication and which when the stem s moved into another position will cut oil communication between the inlet and outlet.

Theoperation of the parts thus far described is as follows: The cup 47 is normally of the rail when the end of arm 39' cup 47 preferablyevens? l in position upon the table .2 as shown in Figs. 1 1-,' 2 and a. The gear of the press when in operation will rotate the gear 15.andcause the shaft 14 to revolve. Gear 16 will transmit rotary motion to the gear 17 and cause the rotation of eccentric 21. This eccentric will swing the yoke 23 upon its pivot 25 and arm 26 will therefore pull on link 34 and carrier 30 so as to draw it longitudinally along the-track 29. At the same time the arm 35 and rod 37 will pull downward on the flange 28 and cause the rail 29 to rock into the positions shown by dotted lines in Fig. 6. A "longitudinally up and down movement oft-he arm 39 is therefore produced and while the carriage is traveling along the rail the gear 40 formed with the arm 39 will travel along the .ins ll and cause the arm 39 to swing lateral'y as shown by. dotted lines in Fig. .4. At the completion of this swinging movement of the arm the carriage 30 will ride on to the lower end of the rail and thereinto the same plane as that originally occupied by it and for the purpose hereinafter set forth. During this swinging movement of. the arm 39 the arm 62w-ill be drawn longitudinally by the yoke'23 and without actusting the valve steni 59 until just prior to the completion of the swinging movement of the yoke 23 and arm 35 whereupon arm 62. will swing the stem 59 soas to establish communication between the valveinlet 53 and outlet 54. A suction will be maintained until ust before all of the parts have been returned to their initial positions by the cam 2Q whereupon the returning arm 52 will shift the valve back to its initial oSition and interrupt the suction. It will t lore.- fore be seenthat the cup 47 upon leaving the table 2 moves upward and forward and then swings laterally to one side of the table and." is lowered. At this. point during the operation the suction islestablished throu h the cup and this. suction continues whi e the movement. of the arm is reversed.by the mechanism described. I As soon as the cup reaches a position, directly above the table 2 during the return niovemeittiof said cup the suction isinterrupted; f l

ranged upon the shaft 14 near its other end is a gear.64wliich.is adapted'to drive delivery mechanism B exactly similar in every respect to the feed "mechanism hereinbefore described and in View of'the fact that both 120 the delivery and feed mechanism are oi the same construction and operate in the same manner it is not deemed necessary to describe said delivery mechanism in' detail. It might be stated that. the arm 39 of the delivery mechanism is normally in position with its cup 47 extended laterally beyondv the table 2 and the valve of its suction apparatus is so mounted that the suction is es tablished imnmdiately' prior to the 'n1o've-. 130

the lateral movement of the cup beyond the table.

Ihave devised for use in connection with the herein described feed mechanism a supply table C which is adapted to automatic ally maintain the top of a stack of paper thereon at a proper level to be contacted by the cup 47 when the same reaches the limit of its outward or lateral movement. As shown in Figs. 1, .2 and 3 this supply table consists ofa' hollow base 65 having a longitudinal opening 66 in the top thereof adjacent which are located guides 67 on which is This slide has a depending ear 69 which engages one end of a threaded rod 70 extending across thefront of the apparatus and having'a crank 71 at one end by means of which the rod can be rotated so as to shift-the slide 68 longitudinally upon the guides 67. The slide 68 has an aperture 7 2 therein and extending, below this a erture is an arm 73 feathered upon a rock 8 aft 74 which extends in front of thea paratus and isprovided' with an arm 75. This arm engages the slotted end of a stem 76 projecting from an eccentric 77 which is mounted on and adapted to be actuated by shaft 14. It is therefore obvious that the rotation of'this shaft 14 will produce a rocking movement of shaft 74 and a correspondsaid arm. is feathered on the rock shaft it will move with the slide 68 during the adjust- A tubularst'andard' 78 isarranged on the having an enlarged opening 80 at the center thereof in which is rotatably mounted a beveled gear 81. This gear has an annular groove 82 into which projects a retaining device such as a screw 83 and a ratchet 84 is formed with or secured to the gear 81 and extends upward therefrom beyond the upper surface of the table 79. Gear 81 is mounted on and engages a screw stem 85 the upper end of which is swiveled to an adjustable table 86 located above the table 79 and'having parallel grooves 8.7 extending in the front edge thereof. A rock shaft 88 is journaled upon the table 79 and has an arm. 89 connected to the arm 73 by means of a rod 90.

Another arm 91 extendsfrom the rock shaft 88 and through a slot 92 in the table 79 and is connected by means of a rod 93 with an arm 94 extending from a -collar 95 loosely surroundingthe upper portion of the stem 85. A 3 ring pressed pawl 96 is pivotally "connecter to. the arm 94 and normally engages the ratchet 84.

It is therefore obvious that the rocking movement imparted to the shaft 74 by eccentric ,77 will result in the rocking of the shaft 88 and the reciprocation of arm 94 and therefore iatchet'84 will be slowly rotated and will cause the gear 81 to move the threaded stem 85 vertically. Ta

ble 86 will therefore be adjusted automatically to a desired ele\ ation. Table 79 has a back 97 extending upward therefrom and provided in its front face with a transversely extending dovetail groove 98 in which is i'nounted a slide 09. This slide is adapted to be secured in adjusted position inany preferred manner as by means of a set screw 100 and carries a guide strip 101 which is slotted longitudinally as shown particularly in Fig. 1 so as to project into the slots 87 without in terfering with the vertical movement of the upper table 86.. This slide and the guide p ate extending therefrom constitutes means for holding a stack of paper-in an upright position. One edge of each-sheet of. paperis adapted to contact with the guide 101 and therefore the pa er of the stack will be always. maintaine with its; edges. in vertical alinement. a l n c" .7 1

- Theforegoing description of theasupply table applies equally as wellto a-re'ceivlng table 1) located at the other side of the apparatus the only difference being that the ratchet 84 is adapted to be actuated by the pawl 96 so as to move the threaded stem 85 carrying the table 86 downward instead of u ward. Moreover, the back 97 of the tab e 79 is not provided with a slide and guide such as shown at 99 and 101.

Should the stack of paper upon the supply inner face of the back, 97 and this slide carries a yoke 104 the upstanding ortions 105 of which have fingers 106 .exten ing at right angles therefrom and ov'erlappingtheupper edge of the back 97. These fingers are spaced apart a considerable distance so as not to mterfere with the proper placing of cup 47. Outstanding lugs 10? are secured .upon the slide 102 and projecting between them isone end of a lever 108 fulcrumed u on the back 97, as shown at 109. This lever ms 'a stop finger 110 projecting therefrom and adapted to move into-the'path of an arm 1 11 secured to one end of a sleeve 112 loosely mounted on therock shaft 88. This'rock shaft has a clutch member 113 having angular teeth upon one face thereof and these teeth areadapted to engage a similar toothed end of the sleeve 112, said sleeve and clutch member 113 being held normally in engagement by a spring 114. This spring bears at one end against a bracket 115 while its other &

end contacts [with the end of sleeve 112. The pawl actuating arm 91 hereinbefore re- I ferred to extends from he sleeve 112 and the spring 1145 holds the clutch members 112 and 113 with suflicient prei aurr to cause the actuation of the pawl by shaft '88, under normal conditions. i p 4 It will be understood that when the shaft 88 is rocked during the actuation of the pawl the arm. 1.11 will be oscillated and as long as the fingers 106 rest upon the upper ed re of the back 97 the iii ger 110 will be disposed out of the nth of arm 111., as shown by full lines in Fig. 8. ll, however, thestack of 1 paper on the fableSij is fed upward against the pawl will cease until enough material has been removed from the stack to permit the fingers 106 to return by gravity to their norrnal positions: i

' As hereinbcforostated the arms 39 and 39 "are normally in the positions shown by full lines in'Fig. 4. Before beginning the operation of the apparatus table 86 is lowered as shown inFig. I and table 86" is raised so as to assume its highest position, When the press is set in motion the table Shearrying the stack of paper will be gradually raisedin the manner herembeforedescribed and table 86 will be gradually lowered. Arms 39 and 39 will be simultaneously raised, swung, and,
